If you're talking about PS/2 keyboards then this is not a general rule.


I'm using a PS/2-keyboard.


It's probably just the strategy implemented in this particular keyboard
controller to handle ghost keypresses. It can not be predicted or
prevented by software on the host computer, atleast not without
intervention from the user.


It's not constant, correct.


As a general rule: PS/2 keyboards handles infinitely simultaneously
pressed keys. You can press them all if you've got enough fingers. But


I just managed to get 8 simultaneous keys:

Really depends on what you press.
